Application filed November 20,1905. Serial No. 288,105.

To all whom it may concern:

Be it known that 1, CHARLES W. llILLEbZ- A BRAND, a citizen of theUnited States, residwhereby motor-cars or other vehicles may be turned,as upon a pivot, in any direction.

The invention consists in the novel construction, combination, andarrangement of parts hereinafter described,,.and pointed out in the.-claims, and in order that itinay be I fully understood referencevillnow be" made to the accompanying drawings, in which Figure 1represents a plan view of the turntable. Fig. 2 is a centrallongitudinal section taken on line H II of Fig. 1. Fig. 3 is a plan viewof a truck-frame employed in carrying out the invention. Fig. 4 is anifregular longitudinal section of a latch and a portion of-a runwayemployed in carrying out the invention, said section being taken on lineIV IV of Flg. 5. oFlg. 5 is an rregular longitudinal section of said latch, taken'on line V V of Fig. 4. Fig. 6 is a vertical Section taken online VI VI of Fig. 5. Fig. 7 is a vertical section of the central postand a casting employed in carrying out the invention, said sectionbeing'taken on line VII VII of Fig. 1.

In carrying out the invention I employ a track 1, preferably annular inplan view. and made in sections .2, so that it may be taken apart andcrated for transportation. Said sections are provided at their oppositesides with laterally-extending ears 3 for'the rception .of lag-screws;whereby the track may be reliably secured to the upper surface of' floorA.. I a

4 designates a plurality of trucks (preferably four in number) made inskeleton fornn each truck being prov ded with a parrot parallel flanges5, a laterally-extendingsocket 6, two pairs of arms 7, providedat' t/heir {enter ends with bearings tl, and a diagonally-eitending arm 9,provlded at its Ollil end with asleeve 10. q

A 11 designates a plurality ofconical-shaped rollers mounted upon axlesllp arranged in bearings 8.

J Guide 20 has a notchQO for thereception of the free end of a gravity-latch22, loosely mounted upon astud 23 and provided 'atjits opposite end with a toot-pre en The-pivotalmovement of saidjlatclris liiliited= l')y stops 2%, integral withthe-ends of rr-segmental rib 25, projecting fronrone end of a -rfiplate26, secured to one edge ol one of the runways by screws 27; a'rodQS;a-washen29, and a nut 30, engaging the tlrireadejda-iouter end oftherod.

Latch 22 is provided. with-tat:segmental.. groove34,which'embraces rib ,-.a-1=1d;- l; us 9 5 prevents the latch fromsliifting-lQugitudinally on the stud. This:construction also permits thelatch to roelesliglitly -o1-1;,the ril) when its free end contacts"withlieep 2 0, and thusrelieves saiddlroe end-toncertain 10 extent ol theshock to \VlllClLlLlq. subjected when stopping the turn-table inalineinept with the runways. Thisrockingmotion is limited by the latchFPIQSSlHg ;l)tl0l}itll5l;i)f.- against spring 33, whiehlatter compressedr0 5 bv reason of the fact that the no-n-ipntumpbf the runways willcarry;their ciliwed .lends "slightly beyond the adjacent endsof the approaches. When the spring expands, it will move the runways backwardlyuntil their ends register with the adjacent ends of the approaches. T

In order that the runways maybe looked after turning a half-revolution,I provide vand the cap, and a clamping-nut 43, engagmg the upperthreaded end of the king-bolt.

Hub 40 is of less height than post 35, so that thecap will not be forcedby the clampingnut into frictional engagement with said hub, and thusprevent it from freely rotating upo the post. 7

Casting 39 is provided with four diagonally-arranged arms 44, projectingfrom the hub and provided at their outer ends with sleeves 45 for thereception of the inner ends of tie-rods 46, the outer ends of whichextend through the sleeves 10. Said rods are drawn to the requisitetension'by means of nuts 47 and then securely locked in the sleeves bynuts 47 and jam-nuts 48. These rods serve to hold the trucks upontrack 1. The trucks are united in pairs by two transverse bars 49,having their ends reliably secured in sockets 6 bybolts 50.

In practice the ends of the runways are normally held in alinement withthe adjacent ends of the approaches by one of the latches 2'2, engagingthe notch in keeper 20. After a vehicle has been run upon the runways itmay he turned ina reversed position by disengaging the latch from thekeeper, which may be readily done by pressing one foot downwardly uponthe foot-piece 24. -The runways may then be revolved until the latchupon the other runway automatically engages the keeper. While therunways are being turned the free ends of the latches are prevented fromengaging the sides of the approaches by guides'21, which will directsaid free ends to the upper surface of angle-irons 15, so that the freeends of the latches may pass over the same without checking the movementof the turn-table.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is 7 1.
